Faits à savoir sur les UV

Introduction

Ultraviolet (UV) rays are part of our everyday environment, even though we can't see them. They come mainly from the sun and can have significant effects on eye and skin health.

Understanding how they work and the importance of adequate protection helps preserve your vision in the long term.

Here's what you need to know about UV rays and why proper protection is essential.

What are UV rays?

UV rays are a form of light invisible to the human eye. The sun is the main source, but UV rays can also reflect off many surfaces: water, snow, sand, concrete, glass, etc. Because they come from all directions, they create constant exposure, sometimes underestimated, but potentially dangerous for the eyes.

Why do I need UV protection?

The damage caused by UV rays is cumulative and often irreversible. Prolonged exposure increases the risk of developing:

• UV-related cataracts

• Growths on the eye (pterygium)

• Certain skin cancers around the eyes and on the eyelids

Protecting your eyes from a young age helps reduce these long-term risks.

What are the adverse effects of UV radiation?

UV rays can cause:

• Premature skin aging

• Wrinkles and dark circles

• Eye diseases

• Increased risk of skin cancer

  
  

Eyes, like skin, are sensitive to the harmful effects of the sun.

Why should I protect my eyes even when it's cloudy?

More than 40% of annual UV exposure occurs when people are not in direct sunlight. Clouds do not completely block UV rays, and many people do not wear protective eyewear on cloudy days.

Clear lenses with complete UV protection can help preserve eye health, even when the sun is not visible.

Why protect the back of the lenses?

UV light doesn't just come from the front: it reflects off surrounding surfaces and can reach the eyes from the back or sides of the lenses. Even though the front surface blocks UV rays, the back surface can reflect these rays back towards the eyes, increasing exposure. Crizal anti-reflective coatings are designed to reduce this reflection and offer more complete UV protection.

Conclusion

UV rays are ubiquitous and can cause significant damage to the eyes over time. Adequate protection—even on cloudy days—is essential to maintain eye health. Appropriate anti-reflective coatings, such as those in the Crizal line, offer additional protection by blocking UV rays from all directions.

To determine the most suitable solution, don't hesitate to consult an eye care professional.
